Build an animated visualization with time series

Context

There is an increasing need for conservation and connection with nature in cities. In this sense, geospatial analysis plays an important role in the effective management of our natural resources.

In this tutorial we are going to represent the distribution of tree species in the streets of San Francisco by color and we will add some interaction through widgets, which will allow us to explore the map by selecting targered filters of interest. In this example, filters are applied by specie and date of planting.

Steps To Reproduce

  1. Go to the CARTO signup page.

    • Click on Log in.

  5. Create a map by clicking on the Create > Create map button on the top. This will open the table as a layer on a CARTO Builder map. Check Creating a map from your data to get started.

  6. Change layer name to “San Francisco trees”.

  7. Change the basemap. Go to Basemaps tab and select “Dark matter” from CARTO.

  8. Click on Layer style to start styling the layer.

  9. Click on the “three dots” icon in the Fill Color section and select “Color Based On” feature species. Pick a palette for a categorical variable (versus a gradient).

  10. Modify the Radius of the points to make them smaller.

  1. Go to Widget tab. If you haven’t created a widget yet, you will see the following page:

    Map widgets add new widget

  2. Add a widget based on the column species. Now we can filter the data based on type of tree.

    Map widgets first widget

    Map widgets first widget_values in

  3. Add a second widget, now based on plant_date. This will generate a time-series widget directly on the map.

    Map widgets second widget

  4. Modify the time window to be “incremental”.

    Map widgets second widget incremental

  5. Now let’s configure the tooltip (or info window). Go to Interactions tab, activate the tooltip and select the field species.

  6. We can make the map public and share it online with our colleagues. For more details, see Publishing and sharing maps.

  7. Finally, we can visualize the result.
